FRANK PETER MORAN, OF CINCINNATI, OHIO.

.DEVICE FOR UTILIZING THE HEAT OF GA-SES DISGIIARGED FROM GOMPR-ESSQRS;

Be it known that I, FRANK PETER MORAN.-

a. citizen of the United States of America,

and resident of 911 West Court street,'Cincinnati, county of Hamilton, and State of Ohio, (post-ofiice address Fifth and Race streets, in the city of Cincinnati, county of Hamilton, and State of- Ohio,) have invented an Improved Device for Utilizing he. Heat of the Gases Discharged from Compressors; andI do hereby declare the following to be a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification.

- My invention relates to devices for utilizing'the heat of the gases discharged from compressors and it has for its object the improvement in the construction of such devices whereby they are simplified and rendered more eflicient in action.

- The novelty of myinvention consists in the combination and sub-combination of the parts as will be hereinafter set forth and specifically pointed outin the claim.

In the drawings the figure is a side elevation partly in section of'the devices which embody my invention. 1

A indicatesan ammonia compressor.

A is the suction ipe and A is the discharge pipe.

B is an ordinary slide valve engine. h 2 is a pipe that leads from the engine B to the heater 0. The pipe B enters the heater from the top forming a coil in the center of the heater and passing out from the bottom of the heater, from whence it passes to the condensers of an ordinary re frigerating plant.

he .heater 0 is composed of two cylinders, one within the other, C is the outer cylmder and C is the inner cylinder; there inder C In the space between the cylinders C? and C hot water or exhaust steam can be circulated. The inner cylinder C has an inlet pipe I) and an outlet pipe D.

gine B to an atmospheric condenser F. The

pipe D also connects with the exhaust pipe E. That portion of the pipe 'D" which con-- nects with the exhaustpipe E, has in it a pressure regulating valve I which can be set so as to allow the gases passing through the pipe D to be kept at any pressure desired. From the atmospheric condenser F, a pipe F leads to a pump G and from the pump G, a pipe D, leads to the heater C.

The pump G has its piston attached to the crank shaft of the compressor A, so that when the compressor runs it causes the pump to run. The crank shaft ofthe' engine B is connected to the crank shaft of the vcompressor A by a coupling H.

The operation of my device is as follows:

I first circulate hot water or exhaust steam in the space between thecylinders G and C of the heater C. This heat converts the liquid ammonia Within the cylinder G into a gas, thereby creating a pressure. This gas is carried by pipe D to the engine B and after it has performed its work in the engine the gas is exhausted through pipe E into the atmospheric condenser F where it is liquefied and passes from. the condenser through pipe F to suction of pump'G and is forced by the pump through pipe Dback into the inner cylinder C? where it is again converted into a gas. The compressor A being connected to engine B by the coupling H, the working of the engine operates the compressor. \Vhen the compressor is working the hot gases from the compressor pass around the jacket of the enginecylinder B and from this, pass through pipe B through the coils located within the inner cylinder C These coils are surrounded with liquid ammonia and the heated gas from the compressor gives up a portion of its heat to the liquid ammonia converting it into a'gasand this gas passes from the heater and goes through the same cycle of operations as that described above.

Having described. my invention what I claim is: e

In a device for utilizing the hot gases from a compressor,. a jacketed, cylinder to receive the hot gases, a coil through which The pipe D leads to the engine B. There is the gas passes from the jacket, the coil 10- an exhaust pipe E, whichleads from the encated within a cylinder and surrounded with lid (min a pipe leading from denser to the tank where the is "genflie top of this cylinder conducting the gas erated, all substantially as descri mt to an e, exha from the FRANK PETER MOB engine into a' condenser, a back pressure v 5 valve 1 een the supply pipe and Witnesses:

the must pipe of H10 engine, a pump to Loy BISSELL,
